Usage
Information After you configure a unicast queue as strict-priority, that particular queue, on the
entire chassis, is treated as a strict-priority queue. Traffic for a strict priority
is scheduled before any other queues are serviced. For example, if you send 100%
line rate traffic over the SP queue, it starves all other queues on the ports on which
this traffic is flowing.
Per-Port QoS Commands
Per-port QoS (port-based QoS) allows you to define the QoS configuration on a per-physical-port basis.

Syntax dot1p-priority priority-value
To delete the IEEE 802.1p configuration on the interface, use the no dot1p-
priority command.
